Keane Lab
Welcome to the Keane Vision & Psychosis Lab
Our brains are faced with the formidable challenge of having to parse and make sense of a kaleidoscope of incoming visual information. Healthy people segment scenes effortlessly but people with psychosis exhibit specific impairments linked to diagnosis, symptom severity, premorbid functioning, and age of onset. A major goal of the lab is to harness tools of behavioral psychophysics, eye tracking, and functional neuroimaging to understand the neural and information processes that underlie visual object perception, both in healthy and psychotic populations.
